Fig. 13 is a fragmentary side elevational view of the flap engaging shoes showing them in operation.

A supporting structure comprising uprights 25, 26, 27, 28 and 29 and the horizontally extending pins 21 and 22 is provided. Secured to the inner face of and extending longitudinally of the pins 21 and 22 are strips 23 and 24. A shaft 30 is journalled in suitable bearings supported by this structure and mounted at opposite sides of the shaft 30 is a sprocket wheel 3l engaging the sprocket chains 32 and 33 which are connected at spaced intervals by the cross bars 34, these chains being endless and operating as a conveyer and passing around the sprocket wheels 67 which are mounted on the shaft 66. A bed 36 is positioned beneath the conveyer adjacent its rearward end and supported by suitable brackets 37 mounted onthe supporting structure. A layer 36, preferably of metal, serves as a wear plate for the table 36. Centrally of the supporting structure is a bed or table 38 which is in alignment with the table 36 and supported by suitable brackets and provided with the metallic covering 38 on its upper surface. A movable table 39 covered with the covering 39 is positioned between the tables 36 and 38. This table 39, as shown in Fig. .3, is supported by brackets 40 and 40 which are connected as shown in Fig. 5 to the cross bars 41 and 42. These cross bars are pivotally connected intermediate their ends to the end of aA yoke 43 projecting outwardly from which is the stem 46 on which is mounted the movable weight 47. This yoke is pivotally connected intermediate the ends of its arms to the cross bars 44 and 45 which are attached to the uprights- 26 and 27. An abutment bar 48 connects the members 44 and 45. yGruide strips 49 and 50 and 7 5 serve to guide the conveyer when it is from the table 39 is an arm 51 which is provided with a pin 52 projected through the elongated slot 53 formed in the laterally eX- tending arm 54. The outer end of the arm 54 is secured in fixed relation to the rod 55 which extends longitudinally of the supporting structure. A bracket 56 is secured to the bracket and projected laterally outwardly therefrom and provided with the upwardly turned end 57 in which is formed 'the opening 58. Projecting outwardly from each of the cross bars 34 at one end are the engagement pins 35 adapted to engage upon passing the angularly turned portion of the rod which is rotatably ournalled in the bearing 64 and provided with the laterally turned crank formin0r member 63 which is pivotally connected to the end of the rod 59 as shown in Figs. 1, 6, and 7. Mounted on this rod 59 is a-collar 60 engaging at one end of which is a spring 61 which embraces the rod 59. This rod 59 projects through a suitable bearing or bracket as shown in Fig. 1 and is in alignment with the opening 58 and normally engages the member 57 and is adapted to enter the opening 58 when the member 56 is moved downwardly to briner the opening 58 into registration with the rod 59. The spring serves to press the rod 59 into the openings 58. A pulley 68 is mounted on the shaft 66 and carries on its face a clutch section 69 cooperating with the clutch section 70 which is non-rotatably mounted on the shaft 66 and which is connected with the rod 55 so that upon a rocking movement of the rod 55 in one direction, a disengagement of theV clutch sections will be effected and a movement of the rod 55 inthe other direction will move these clutch sections into engagement. A belt 71r connects the wheels 68 with the pulley 72 which is mounted on the shaft 73 of the electric motor 74. The motor 74, when the clutch sections are in engagement, serve to effect a travelling of the conveyer and when the clutch sections are disengaged the conveyer remains stationary. The table 39 is rockably mounted and when sufficient weight is placed thereon it will be moved downwardly rocking the member 43 and raising the weight 47 By adjusting the position of the weight or regulating the size of the weight 47, the weight necessary to rock the table 39 downwardly may be determined or regulated. When the table 39 rocks downwardly, the arm 54 will be rocked to effect a rotation of the shaft 55 so as to throw the clutch sections into mesh so that a travelling of the conveyer is effected. When the table .39 springs upwardly, it will project above the path of travel of the cross bars 34 and lock the conveyer against further movement. At the same time, the shaft 55 will be rocked to disengage the clutch sections. A space 77 is formed between the guide strips 23 and 24 i and the edge of the table or bed 36, the table 39 and the bed 38 being of the same width as the bed or table 36. In use, I prefer to use a carton formed from cardboard and having the side flaps 78 and 79 and the end flaps 80 and 81. In placing the carton in position,

the end flaps 80 and 81 are folded inwardly7 as shown in Fig. 6, the side flaps 7 9 and 78 depending and projecting through the space 77. Supported on the super-structure at opposite sides are the curved engagement members or guides 82 which serve to guide the side flaps 78 and 79 so as to contact with sprocket wheels 83 and 85 carried on the ends of the shafts on which are fixed the roller brushes 84 and 86, respectively. These roller brushes contact with the perforated portion 88 of a passage 87 which serves to conduct against the roller brushes adhesive material such as glue or the like from the containers 89 so that as the carton is carried past these brushes, the end flaps will be coated from their inner surface with glue or other adhesive material. Guide members 90 are projected below the end of the table bed 38 and curved so as to engage the side fiaps 78 and 79 and fold them inwardly as the carton travels, the covering of the bed 38 terminating in a V-shaped tongue 92 so that as the cartons are carried forwardly they are brought into horizontal position and pressed against the extension 91 of the guide strips 90. At opposite sides of the supporting structure above the bed 38 are positioned roller brushes 93, each having a sprocket `gear 95 or 96 engageable with the side of the carton so that a rotation of these brushes is effected. The perforated pipe 99 forms an extension of the pipe 98 and serves to conduct adhesive material from the container 97 against the brushes. A folding strip 101 is provided at opposite sides of the structure to engage the side flaps of the carton which project forwardly from the upper edge and fold them inwardly so as to bring them under the presser member 102 which is secured t0 7 the cross bar 103 slidably mounted on the studs 104 upon which is mounted a washer 105- engaging the coil spring 106. The presser member 102 is thus floatingly mounted. Guide strips 107 are mounted at opposite sides to fold the side flaps inwardly.

Mounted on a standard 108 is a rotatable hub 109 having arms 110 projecting outwardly therefrom, each provided at its end with a pivotally mounted shoe 111 normally held by the spring 112 in outwardly directed position. As the cartons are led through, these shoes will engage the end flaps and serve to press them downwardly and the shoe 113 will serve to retain them in downwardly pressed position until the side flaps are folded over and glued thereto. After the passage of the carton beneath the presser 102, it passes between the presser belt 116 which is mounted on the rollers 114, these rollers being carried ina frame 117 slidably mounted on the pins adapted to pass around the rollers 127 and 127', a chute 123 projecting outwardly from one side so as to discard the commodities such as apples or potatoes which may pass through the sorting belt 122. The roller 127 is i `mounted on the shaft 126. Mounted centrally on the shaft 129 is a gear 143 over which passes the chain 144, this chain also passing over the gear 139 mounted on the shaft 138. This chain 144 is provided with the cross bars 145 at spaced intervals to provide a conveyer, this conveyer passing over the guide board 142 and projecting at its lower end beneath the sorter 122. Side members 148 extend at opposite sides of this conveyer and terminate in a guide 149. Fixedly mounted on the shaft 129 is a sprocket gear 130 which is connected by the belt 131 to a sprocket gear 132 mounted on the shaft 133 which is journalled on the platform 136 which serves to support the motor 74. A pinion 134 lixedly mounted on the shaft 13.3 meshes with the gear 135 liXedly mounted on the motor shaft 73. The uprights 26 and 27 are extended to provide the upwardly projecting portions 146 and 147 which are connected by the longitudinally extending bars 150 and 151. Mounted on these bars 150 and 151 is a supporting bar 152 connected at opposite sides between hooks 153 and 153 to the legs 154 and 155 of a U-shaped member having a bight 156 projecting outwardly from which is a threaded stud 157 carrying the weight 158 threaded thereon. Rods 159 and 160 connect the legs 154 and 155 to a U-shaped member 161 carrying rollers 162 and adapted to engage between the sides walls 163 and 164 of a drum which is provided with the partitions 165, 166, 167 and 168 so as to divide this drum into a plurality of compartments. The drum is rotatably mounted on the axle 169, this axle being projected through and journalled in a supporting frame comprising the lower rail 170, the upper rail 171 and the side rails 172 and 173, a pair of these supporting frames being provided, one at each side of the drum. These frames are connected pivotally by the hooks 174 to the legs 154 and 155 between the end of the U- shaped member and the point of connection of the hook 153 therewith. A guide chute 178 is positioned forwardly of the drum, A test scale 175 serves as an extension between the tables 38, 39 and 36.

In operation, the commodity after being placed on the sorting belt 122 is rotated so as to fall into the hopper 123 or onto the guide board 142. The conveyer formed from the chain 144 and the cross bars 145 will serve to convey the commodity forwardly so as to deposit the same in one of th-e compartments of the drum. The member 161 will prevent rotation of the drum in one direction and the dog 179 will prevent rotation in the opposite direction. By adjusting the position of the weight 158, the amount of material to be deposited in the drum nece."- sary for effecting a rocking of the U-shaped member having the legs 154 and 155 may be determined. Vvlhen this U-shaped member is rocked, the member 161 will be disengaged from between the discs or side walls 163 and 164 and since the material placed in the drum will be beyond center, the drum will rotate so as to deposit the material into the container resting on the movable table 39. This movable table will then move downwardly so as to rock the clutch into operative position. At the same time the rod 59 will be brought into alignment with the opening 58 and the table 39 held in downward position, thus permitting a travelling of the conveyer 32. As the cross bars 34 are brought into position so as to engage the pins the rod 59 will be retracted out of engagement with the opening 58, thus releasing the table 39 for movement into upward position to lock the belt comprising the members 32 and 34 against further travel and disengage the clutch. When the next compartment of the drum is filled, the same operation will take effect.

In this way, I have provided a simple and effective means for packing and sorting and sealing various commodities and particularly adapted for use in packing potatoes.
